Purpose of Unit: The purpose of this unit on stoichiometry is for students to understand the quantitative relationships between products and reactants in a chemical reaction. This unit includes mole-mass relationships, the law of conservation of mass, balancing chemical equations, stoichiometric mole conversions and stoichiometric calculations, limiting reactants, and percent yield. This unit falls directly after the units on chemical reactions and the mole and it will take place in late February/ early March. I have chosen with my CT to plan my unit on Stoichiometry because it is a difficult subject to teach and to learn. I feel like it will benefit me in the long run if I spend a significant amount of time preparing this unit and getting as much feedback as possible.
I plan on using many methods of instruction in this unit. I will start each class with a warm-up question; some questions reviewing what we did the previous day, and some questions about new topics to assess prior knowledge. I would like to introduce each sub-topic with a PowerPoint presentation to summarize and demonstrate the major concepts and then move into activities and experiments to practice these learned concepts. I plan to incorporate technology into this unit by asking my students to create a concept map on the computer at the beginning of the unit and then ask them to revise and improve their concept maps at the end of the unit. I would like to focus a significant amount of time on balancing chemical equations because it is crucial to understand for the rest of the unit. One activity for practicing balancing chemical equations is to use colored M&Ms to represent different elements in reactions so students can visualize how many of each element is needed in the reactants and products of the balanced chemical equation.
